Num and caps lock flashing, laptop freezing

When laptop freezes there's a horrible noise that comes out the speakers, the screen freezes up completely and some times goes all fuzzy, and the NUM and CAPS lock lights flash. After about 2 mins the computer restarts and works again for any time between 5 mins and a hour.

Hi alanneil19

Sounds to me like you have a virus or other malware in your laptop
Follow these steps and I believe your problems will be solved, if not then look for something mechanical/electrical wrong with the computer.
***********************************************************************
To remove a virus,trojan,worm,etc from your computer...do it the EASY way...let someone else do it for you.
Start your computer in the Safe Mode
To do this you will do the following
As the computer is starting keep tapping the F1, F2,F10 or F8 Key depending on your computer.
This will start the computer in the Safe Mode.
Once in the safe mode go to the following webage below and download,install, and run Microsoft Safety Scanner for FREE.
Once you run the Microsoft Safety Scanner (it may take quite a while depending on the size of your hard drive) it will remove all the virus's,trojans,worms,etc it finds, if it does not completely remove them all you will be given a chance to chat with a Microsoft Professional thru a pop open window and he will take control of your computer (with your permission) and finish removing all the rest of the virus's, trojans, or worms that are on your computer for FREE!! Can't beat FREE!!
Please take time to rate me

In dell inspiron 1525 laptop, all light blinking but display not coming


If you mean that your Num lock , Caps lock, and Scroll lock LED's are all flashing then this indicates there is a problem with your motherboard.

Press power button nothing comes up on screen, however, the num lock icon lights up and flashes, the caps lock icon also lights up. Dell Vostro 1510.


Copy and paste this link into your internet browser for the service manual for your laptop.
http://support.dell.com/support/edocs/systems/vos1510/en/SM/html/trouble.htm#wp1092170
The star icon (*) means flashing LED, the bold circle means on, the circle within a circle means off.
The LED's that they are referring to are the NUM, CAPS and SCROLL.
It appears that you have a problem with your LCD. Try connecting an external monitor to your laptop. If you get a display then your LCD display panel needs to be replaced. If no display then your motherboard needs to be replaced.
